JTWC提升評級至Medium

(1) THE AREA OF CONVECTION (INVEST 99W) PREVIOUSLY LOCATED
NEAR 22.3N 127.0E, IS NOW LOCATED NEAR 22.8N 127.1E, APPROXIMATELY
195 NM SOUTH-SOUTHWEST OF KADENA AB, OKINAWA, JAPAN. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A COMPACT AND
PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH FLARING
CONVECTION BEING SHEARED TO THE NORTH DUE TO 15 TO 20 KNOT SOUTHERLY
VERTICAL WIND SHEAR (VWS). A 070133Z ASCAT PARTIAL PASS SHOWED AN
ORGANIZED LLCC WITH 15 TO 20 KNOT WINDS ALONG THE EASTERN PERIPHERY.
EXPECT CONVECTION TO CONTINUE TO FLARE OVER THE LLCC DUE TO GOOD
DIVERGENCE ALOFT, ASSISTED BY A TUTT CELL TO THE NORTH, AND WARM SEA
SURFACE TEMPERATURES. GLOBAL MODELS MAINTAIN A WEAK LLCC THAT SLOWLY
TRACKS NORTHWESTWARD TOWARD TAIWAN OVER THE NEXT THREE DAYS. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. DUE TO THE WELL
DEFINED LLCC AND MARGINALLY-FAVORABLE ENVIRONMENT, THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO MEDIUM.

JMA持續判定為熱帶低壓


中心已經在浙江溫州近岸，等等就會登陸


JTWC取消評級

(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 27.5N
124.5E, HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE DEVELOPMENT
OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
